What is intermittent spark ignition?

What is intermittent spark ignition?

Intermittent Pilot Ignition is an electronic system, which uses an electrode to ignite the pilot gas. In turn, the pilot flame lights the main burner gas. The term Intermittent is used because the pilot burner flame is only present when the main burner is operating.

How does Intermittent pilot Control Work?

Rather than keep a flame burning all the time, the intermittent pilot only lights when needed. The system responds to the command for heat by using an electric spark to ignite the flame. A sensor registers the flame and lights the main burner, at which point the pilot light goes out.

How can the safety lockout be reset?

Though lockout mode errors and resets do vary from manufacturer to manufacturer, most use a simple reset procedure that involves turning power off to the furnace for thirty seconds or longer and turning it back. The interrupted power supply clears the lockout and will allow the unit to attempt normal operation again.

How do you reset an automatic pilot light?

Press the gas control knob down all the way and hold it in the depressed position. If you have no igniter, move the match or barbecue lighter flame to the end of the pilot tube; the pilot flame should light immediately.

How do I know if my spark ignitor is bad?

Here are a few steps to check your ignitor and determine if it needs to be replaced.

  1. Make Sure The Furnace As At Room Temperature.
  2. Turn Off The Furnace.
  3. Switch Off Circuit Breaker.
  4. Remove Furnace Service Panel.
  5. Look For Visible Damage.
  6. Remove Ignitor Wires From Socket.
  7. Test The Ignitor With A Multimeter.

How do you test a spark ignition module?

Remove one plug wire at the spark plug and insert an old spark plug into the end of the plug boot. Place the spark plug on a metal surface on the engine. Crank the engine and check for a spark at the old spark plug. No spark on the plug indicates an ignition problem.

How are most intermittent pilots lit?

Most modern furnaces use an intermittent pilot, in which gas is fed to the burner assembly as needed, and it is lit via a spark or hot surface ignition. Hot surface ignition uses silicon carbide, a material that reaches extremely high temperatures when energized, up to the ignition temperature of gas.
